This work was conducted during 2014&2015 seasons on young Manfalouty pomegranate trees grown in reclaimed sandy soil under drip irrigation (National Research Center orchard) at Nobaria region, Behara Governorate to investigate the possibility of replacing the expensive mineral NPK fertilizers commonly adopted in the region with other cheaper and environment friendly alternative sources. In this regard organic N and some natural raw PK materials mixtures used at 3 doses (500,1000,1500 and 2000 g/tree) either solely or combined with bio NPK fertilizers mixture were evaluated through the response of vegetative growth and nutritional status measurements. Data obtained displayed that the investigated growth measurements (plant height, stem thickness, shoot length, No. of both shoots per tree & leaves /shoot, average leaf area and total assimilation area), as well as nutritional status (leaf chlorophyll, N, P, K, Fe, Mn and Zn contents) responded obviously to investigated fertilization treatments and followed to great extent the same trend. Herein, control, organo NPK rocky materials only at 500 g/tree and bio NPK fertilizers mixture solely at 300 ml/tree seemed to be equally the same, ascendly followed by (T3- 1000g of alter. organo. Rocky mix. Only, T6 - (T2 + 300 ml bio NPK mix.), (T4- 1500g of alter. organo. Rocky mix. Only &T7-(T3 + 300 ml bio NPK mix.), (T5- 2000g of alter. organo. Rocky mix. Only) and T8 - (T4 + 300 ml bio NPK mix.)/ T9 - (T5 + 300 ml bio NPK mix.). Consequently, mixture of organic N and rocky PK materials at either 1000 or 1500 g/tree combined with bio-NPK mixture at 300ml/ tree could be safely recommended, as their beneficial effects on both growth & nutritional status measurements were concerned.

In order to study effect of sowing dates of some bread wheat genotypes on agronomic, growth, germination, seedling growth and quality characteristics. A field and laboratory experiments were carried out during 2010/2011 and 2011/2012 seasons. Three sowing dates starting from 20th November to 30th December with 20 days intervals and eight wheat genotypes. It could be noticed that delaying sowing date to 30th December resulted in the lowest number of days to maturity, grain yield, germination percentage, germination index, seedling length, seedling vigor index and seedling dry weight as well as protein percentage and gluten quality in both seasons. Misr 1 variety had a significant and highest grain yield compared with the other genotypes in both seasons. Also, it had a significant increment of germination and seedling traits followed by Gemmeiza 11, Line 2 and Line 1 genotypes. Line 2 recorded highest values of crude protein content, wet and dry gluten percentages followed by Misr 1 and Shandweel 1 varieties in both seasons. Tested genotypes could be discendingly arranged according to their grain yield/ha as follows: Misr 1, Line 2, Line 1, Gemmeiza 11 and Shandweel 1. The highest grain yield/ha resulted from planting Misr 1 variety under all sowing dates. The maximum quality measurements were obtained by Line 1 when planting on 20th November in both seasons. It may be recommended that planting Misr 1 to maximize the productivity per unit area while in case of delay in sowing date recommended planting Line 1 or 2 to maximize the unit area yield quantity and quality.

Greenhouse experiment was conducted to evaluate the pathogenicity of root rot fungi on faba bean plant. Lab. experiment was also conducted to study the effect of organic compounds and fungicide Rizolex-T50 on the linear growth of the tested pathogenic fungi. Two field experiments were also carried out to study the effect of organic compounds with different concentrations and fungicide Rizolex-T50 on reduction of root rot and enhancing some morphological, physiological characteristics and productivity of faba bean under saline affected soil conditions during 2013/2014 and 2014/2015 seasons. The results under greenhouse conditions indicated that all tested pathogenic fungi caused emergence damping-off. Rhizoctonia solani was the most effective in pre-emergence damping-off while, Fusarium solani gave the highest percentage of post-emergence damping-off. The pathogenic fungi caused anatomically deformation in root structure. Infected root with F. solani caused complete destruction of epidermal cells followed by degradation of cell wall in the cells of cortex. In vitro, Rizolex-T50 completely inhibited the growth of the tested pathogenic fungi. On the other hand, chitosan at 8 g/L was the most effective in reducing fungal growth followed by proline at 200 ppm. In vivo, the application of organic compounds counteracted the harmful effects of salinity. Humic acid highly reduced pre- and post-emergence damping-off and subsequently increased field emergence %. The high level of proline (200 ppm) was more effective in increasing morphological measurements (plant height, No. of branches and leaves/plant) and photosynthetic pigments i.e. chlorophyll a, b and carotenoids. While, the high concentration of HA (2000 ppm) significantly increased No. of pods/plant, seed yield/plant and 100-seed weight. Chitosan gave the highest phenols content followed by proline treatment. The high increase in carbohydrate content occurred under low level of HA (1000 ppm), followed by high level of proline (200 ppm). The efficacy of the tested organic compounds in control of root rot disease was reflected on the plant causing increase in yield components. It is suggested that pre-sowing seed soaking with HA (2000 ppm) or chitosan (8 g/L) or proline (200 ppm) could be considered as alternative fungicide for controlling root rot disease and increasing productivity of faba bean under salinity and natural infection conditions in the field.

Half diallel crosses among six genotypes of rice (Oryza sativa L.) as well as their parents were cultivated in a randomized complete block design to investigate general combining ability (GCA) effects of parents and specific combining ability (SCA) effects of crosses during different sowing dates. Analysis of variance in diallel analysis exhibited highly significant (P < 0.01) for most studied traits at the four sowing dates. The mean squares due to GCA and SCA were also highly significant for all studied traits during the four sowing dates, indicated that the importance of the both additive and dominance gene actions for these traits. Variances due to GCA were greater than these due to SCA for days to heading, panicle length and panicle weight traits during the second, third and fourth sowing dates and for grain yield/plant during the first and second sowing dates. However, the values of SCA variances were higher than the values of GCA variances for the other studied traits through the other studied sowing dates. Results showed significant differences among all the crosses means and their respective parental values for all examined traits at the four sowing dates. The most of parents and their F1 crosses were displayed significant or highly significant GCA and SCA effects either negative for days to heading or positive for the other studied traits at the four sowing dates. Concerning the four sowing dates, the variety Giza 179 was the best general combiner for days to heading, grain yield/plant, number of panicles/plant and 1000-grain weight traits while, the genotype CT 9882 was the best general combiner for panicle length and panicle weight traits. The best specific combinations during the four sowing dates were the cross Giza 178 x CT 9882 for days to heading and number of panicles/plant traits, the crosses Giza 178 x Sakha 105, Giza 178 x Sakha 106 and Giza 178 x Giza 179 for grain yield/plant and 1000-grain weight traits and the cross Giza 179 x CT 9882 for panicle weight and panicle length traits. Cluster analysis based on all studied traits resulted into two clusters from genotypes through all sowing dates in rice. The first cluster included the two exotic genotypes (CT9882 and CT 9506). The second cluster containing four genotypes, further divided into two sub clusters. Sub cluster-I containing the most earlier rice genotypes (Sakha105 and Sakha106). The Egyptian indica rice varieties (Giza178 and Giza179) were grouped together. The results of cluster analysis suggested that there is genetic diversity among the six genotypes for all studied traits. Hybridization among these genotypes in the two groups provided more possibility to having more genetic diversity and could be used in breeding programs to achieve maximum heterosis as well as earliness and yield improvement in rice. Generally, the parents involved in the previous combinations and the best crosses could be use in initiated the breeding program for growing at early sowing dates (first and second sowing dates) of rice crop in the north of Egypt.

Pelargonium zonale cv. ʺBelmonte Redʺis a popular as flowering pot plant with attractive flower heads ,leaves and
a wide range of floret color. The present investigation was carried out during two successive seasons of 2012 and 2013 at the Experimental Greenhouse and Post-Harvest Lab. of Ornamental Plants and Landscape Gardening Res. Dept., Hort. Res. Inst.; Giza, Egypt, to investigate the effect of spraying solutions of (GA3 and distilled water) on pelargonium rooted cuttings after planting (0- time) and cold storage in perforated and imperforated polyethylene bags for 4 and 8 days at 5°C and their interactions to maintain the quality during shipment. Results showed that all treatments significantly stimulated most of the studied characters compared to control in both 0-time and after cold storage. Spraying pelargonium rooted cuttings with GA3 at 200 mg/l significantly increased vegetative, flowering and root growth parameters in both 0-time and after cold storage. Also, the same treatment recorded higher values of both total chlorophylls and total carbohydrates and lower carotenoids contents in the leaves in both 0-time and after cold storage. Regarding rooted cuttings spraying with GA3 at 200 mg/l and stored for 4 days at 5 °C, it was noticed that the pelargonium rooted cuttings stored for 4 days recorded significantly higher values of vegetative, flowering and root growth parameters than those stored for 8 days. In respect to packaging, it was noticed that the pelargonium rooted cuttings in imperforated polyethylene bags were better in all the studied characters than those stored in perforated polyethylene bags. Rooted cuttings sprayed with GA3 at 200 mg/l then stored for 4 days at 5 °C decreased both weight loss, ethylene production, respiration rate and gray mold infection moreover, improved visual rating. The results of interaction showed that spraying rooted cuttings with GA3 at 200 mg/l and storing them for 4 days gave the lowest respiration rate and ethylene production. Moreover, the rooted cuttings sprayed with GA3 at 200 mg/l and stored for 4 days in imperforated polyethylene bags gave the significantly highest records of vegetative, flowering and root growth parameters and reduced the depletion of total carbohydrates and pigments contents in the leaves. Also, the same treatment gave the utmost decreasing in the decay caused by Botrytis cinerea and the least weight loss percentage which in turn increase quality.

The present work was conducted during 2015 and 2016 seasons at the Tropical Farm, Aswan Botanical Garden, Agric. Res. Inst. to study the possibility of propagated Chrysophyllum oliviforme L.vegetatively. Semi- hardwood cuttings from juvenile (3 years old) and mature (30 years old) C. oliviforme trees were used to test their prospect to form the adventitious roots. The growth media consisted of 2:1 peat: perlite (v: v) ratio and the base of cuttings were soaked for 24 h. in different IBA concentrations (0, 1000, 2000, 4000 and 5000 ppm). The obtained results showed significant differences in the root and shoot development of cuttings with a higher rooting parameters forthe young than mature trees. Using the high hormone concentrations (4000- 5000 ppm) increased the rooting percentage and growth parameters compared to the low concentrations (1000- 3000 ppm). However, the anatomy of cuttings postulate that sectors of mature trees had a thicker stripe of xylem vessels and additional cell layers of sclerenchyma than sectors from juvenile trees. Also, cambium was more differentiated with high activity in young trees than in the mature one. You can say that the presence of a continuous sclerenchyma layer can work as a physiological partition to the emerging root and increase with the aging of the tree.

A field experiment was conducted during 2014 and 2015 seasons at El-Sirw Agricultural Research Station, Damietta, Egypt. The present study was conducted to identify the response of rice cultivar Giza 179 to phosphorus (P) and sulfur (S) fertilizers application under saline soil conditions. The average of salinity levels of experimental site were 7.9 and 7.5 dS m-1 in 2014 and 2015 seasons, respectively. Split plot design with four replications was used. The treatments comprised the response of rice cultivar Giza 179 to four phosphorous rates namely; 0, 36, 54 and 72 kg P2O5 ha-1 and four sulfur rates viz; 0, 120, 240 and 360 kg S ha-1. Some growth characteristics, grain yield and yield components of rice were estimated. However, the economic evaluation was assessed. The main results could be summarized as follows; the P and S treatments significantly improved rice growth criteria i.e. leaf area index, chlorophyll content, dry matter production, number of tillers hill-1, plant height, yield components; number of panicles hill-1, panicle length, panicle weight, number of filled grains panicle-1 and 1000-grain weight, grain and straw yields and harvest index compared to control treatment. The treatment of 54 kg P2O5 ha-1 gave the highest values of all above mentioned traits and also, the treatment of 240 kg S ha-1 gave the highest values of them without any significant difference with 120 kg S ha-1. The interaction between P and S significantly affected LAI, plant height, number of panicles hill-1, grain and straw yields especially with the combination of 54 kg P2O5 ha-1 and 240 kg S ha-1. From economic evaluation, the highest grain yield increase over control (t ha-1), profitability (LE ha-1) and net return were obtained with the treatment of 54 kg P2O5 ha-1 and 120 kg S ha-1. It sum up that application of 54 kg P2O5 ha-1 and 120 kg S ha-1 is enough to obtain higher grain yield and economic return under the present study and similar conditions.

Two field experiments were carried out at Mansoura Agriculture Research Station during the two seasons of (2014 / 2015) and (2015 / 2016) to study the effect of spraying micro elements in combination with Bio. and organic fertilization on garlic production. The treatments tested are Zn at 60 Ppm , Mn at 60 Ppm , Fe at 80 Ppm and Zn + Mn + Fe at 60 – 60 – 80 Ppm respectively were sprayed on garlic plants grown in plots treated with Bio fertilizer ( Nitrobin + Phosphorin ) and combined with organic fertilizer at rate of 10 m3 / Fed . + 50 % of the recommended dose of chemical fertilizer and 100 % chemical fertilizer. The results indicated that chemical fertilizers at 100 % and 50 % (FYM) + 50 % chemical fertilizers have insignificant effect on plant height, bulbing ratio and bulbing diameter in the two years. While number of leaves and neck diameter were higher in the first season .as affected by 50 % (FYM) + 50 % (chemical fertilizers). Moreover 100 % chemical fertilizers give less yield than 50 % (FYM) + 50 % (chemical) in the two years. Bio - fertilizers treatments give higher yield than treatments without Bio fertilizers. However, number of leaves was higher in the Bio fertilizers treatments but neck diameter, bulbing diameter and bulbing ratio were not affected in the two yearsAs for spraying with microelements (Zn, Mn, Fe) all parameters were affected significally in the two years. Since microelements give rise to higher values in vegetative growth and total yield (Ton / Fed). The results indicated that the triple interactions have no effect on all vegetative growth parameters in the two years but total yield was affected significally in the two years. Finally spraying garlic with (Zn + Mn + Fe) gives the highest yield under application of (nitrobin + phosporin) in combination with 50 % FYM + 50 % chemical fertilizers.

Two field experiments were carried out on clay soil in El-Gemmeiza Agricultural Research Station, Agricultural Research Center, El-Gharbiya Governorate, Egypt during 2013 and 2014 seasons to study the effect of five potassium treatments and four foliar applications with Zinc and Manganese on growth, earliness, yield, yield components and fiber quality of Egyptian cotton cultivar Giza 86 (Gossypium barbadense, L.). The experimental design was a split-plot with four replications. The main plots involved the five potassium treatments namely; A- Soil application of 24 kg K2O/fed. as potassium sulfate at thinning, B- Foliar application of 5 kg potassium sulfate/fed., C- Foliar application of 2.5 g potassium citrate/L., D- Foliar application of 500 cm3 potassium humate/fed. and E- Foliar application of 2.5 cm3 potassium silicate/L. and the sub plots involved the four foliar applications of Zn and Mn namely; 1- Control (without foliar application), 2-Foliar application of Zn-EDTA, 3- Foliar application of Mn-EDTA, and 4- Foliar application of Zn-EDTA + Mn-EDTA. The timing of foliar applications was at the start of flowering and 15 days later. The most important results obtained could be summarized as follows: 1-The potassium treatments gave significant effect on plant height at harvest, no. of internodes and sympodial/plant, no. of open bolls/plant, boll weight, seed index and seed cotton yield/plant as well as /fed. in both seasons and lint percentage in the second season only, in favor of foliar application of 2.5 cm3 potassium silicate/liter water. Also, potassium treatments gave significant effect on internode length in both seasons, in favor of foliar application of 2.5 cm3 potassium silicate/liter water. On the other hand, the potassium treatments gave insignificant effect on first sympodium node, days to first flower, upper half mean length, uniformity index, micronaire reading and fiber strength in both seasons.2- Foliar application with Zn and Mn treatments gave significant effect on plant height at harvest, no. of internodes/plant, internode length, no. of sympodia/plant, no. of open bolls/plant, boll weight, seed index and seed cotton yield/plant as well as /fed. in both seasons and on lint percentage in the second season only, where the superiority was found in favor of applying Zn and Mn in mixture at one level for each (2 g/L water) twice at the start of flowering and 15 days later. However, insignificant effect was obtained due to these treatments on first sympodium node, days to first flower, upper half mean length, uniformity index, micronaire reading and fiber strength in both seasons.3-The interaction between potassium treatments and foliar application of Zn and Mn treatments gave a significant effect on plant height at harvest, no. of internodes/plant, internode length, no. of sympodia/plant, boll weight and seed index in both seasons and no. open bolls/plant, seed cotton yield/plant as well as /fed. in the second season only, where the highest values of these traits were obtained from foliar application of 2.5 cm3 potassium silicate/liter water and foliar application with Zn and Mn in mixture contains 2 g/L water from each element twice (at the start of flowering and 15 days later). This interaction gave insignificant effect on first sympodium node, days to first flower, lint percentage, upper half mean length, uniformity index, micronaire reading and fiber strength in both seasons.

This study was conducted during two seasons 2014 and 2015 to evaluate the effects of spraying natural moringa leaf extract, silicon and their combination on vine vigor, yield and fruit quality of "Flame seedless" (Vitis vinifera L.) grapevine grown in a private vineyard located at El-Beheira Governorate. Seven treatments were done, control (spraying with water), silicon at 0.1%, moringa extract at 2%, and silicon at 0.1% plus moringa extract at 2%. All treatments were sprayed in two ways (2 times only and every 2 weeks) starting at 15-20 cm of shoot length. The obtained results revealed that the suggested treatments were effective in stimulating different growth parameters, yield, and fruit quality[G1] parameters. Moringa leaves extract at 2% combined with silicon at 0.1% every two weeks significantly enhanced vegetative growth parameters in terms of leaf area, total chlorophyll, average shoot length, cane internodes length, [G2] and their diameter, and removed pruning weight, leaf nutrients content as N, P, K, Fe, Zn and Mn. Also cluster physical quality parameters in terms of weight, length, width, berry physical parameters as weight and volume of 100 berries, firmness, berry removal force, berry length and diameter consequently and juice chemicals in terms of SSC, SSC/acid ratio, anthocyanins and total sugars contents are also increased. Sequently, it increased the total yield per vine and reduced titratable acidity.
